3-5. Power supply unit [PAC-SC51KUA]
PAC-SC51KUA supplies DC power of M-NET (22-30V) and 24V at TB2 and TB3 respectively; the former is for centralized
transmission use and the latter is for AG-150A operation and LAN function use.
1. When using PAC-SC51KUA as the power supplier for system controller, the capacity for system controller is
considered as follows.
Lossnay can have its own Lossnay remote
controller, but the total quantity of the controllers
is limited.

Fig. 1 Equivalent power consumption of controllers
In this case, pay attention to leave the power supply switch connector on CN41 of the Outdoor unit as the factory setting
before shipment.
Taking the power consumption of the control board of Indoor unit as 1, the power consumption of various controllers is rated
at Table 1.

Table 1 Equivalent power consumption of controllers
PAC-SC51KUA is capable to supply equivalent power up to 5, therefore the maximum connectable number of system controller
is as follows.
*1: According to the system restrictions, PAC-SC51KUA can be connected to only one centralized controller.
As the air conditioner control system may combine all kinds of system controllers, the total power
consumption of system controllers need to count with Table 2.
For example, the controller system contain 1 AG-150A, 2 ON/OFF remote controllers (PAC-YT40ANRA),
and 6 Lossnay remote controllers connected at centralized control communication line.
Then the total power consumption is
1 x 0.5 + 2 x 1 + 6 x 0.25 = 4.0 < 5.
One PAC-SC51KUA is therefore enough. The total power consumption should not exceed 5.
